Re: Upgrade to potato impossible?
oye. how about this. it's pure bourne shell, not full of *#%$&@! evil
bashisms. even works on solaris, irix, linux... wrap it in a function
if you must.
job
#!/bin/sh
pwd="/bin/pwd"
if [ -h "${1}" ]; then
# hmm, symbolic link, kinda messy
# grab what the link points to, and reset $1
# BUG - if ${1} has a space in it, this will fail.
set -- "`ls -l "${1}" | awk '{print $(NF)}'`"
fi
file=`basename "${1}"`
if [ -f "${1}" ]; then
cd `dirname "${1}"` 2> /dev/null || exit 2
dir=`${pwd}` # /bin/pwd returns absolute paths
echo "${dir}/${file}"
elif [ -d "${1}" ]; then
cd "${1}" 2> /dev/null || exit 2
dir=`${pwd}`
echo "${dir}"
exit 0
else # umm, something funny here, bail out
exit 1
fi
